Congresswoman Corrine Brown is unequivocal when it comes to advising her party's Presidential candidate on how to beat George Bush.

"Mr Kerry is a nice man," she begins, "he's an officer and a gentleman, but he is in a war with a bunch of thugs and he's got to understand that he is fighting like he's fighting the mafia ... I want him to cut his [Bush's] heart out if he has to".

As more than 100 million Americans prepare to go to the polls, Panorama presents a compelling portrait of an increasingly bellicose, nail-biting, billion dollar Presidential campaign and examines how the two main parties are pulling out all the stops to mobilise America's powerful voting blocks.

The team reports from Florida, scene four years ago of one of the most controversial episodes in US political history when Republicans took the White House by just 537 votes.

In Orlando, home to Disneyland's Magic Kingdom, local political campaigners tell Panorama they've renamed the town 'Ground Zero' as they 'go to war' over the critical undecided voters in the largest swing state.

At the local campus, documentary film maker Michael Moore is the latest celebrity activist to roar into town on his 'Slacker Uprising tour'; he tells Panorama that he secret admires the Republicans' disciplined election machine.

But, as John Kerry answers Corrine Brown's call and tells the people of Orlando he's now 'carrying a big stick' to take on his opponent, Panorama explores how George Bush has consolidated one of his most powerful bases, evangelical christians, over the issue of gay marriage.
